Which reaction removes hydrogen ions from the blood?
carbon dioxide
How can you determine rate of rxn of a rxn mechanism having fast equilibrium?
You can determine the rate of a reaction mechanism having fast equilibrium by the number of hydrogen ions that are present. If the reaction has a high number of hydrogen ions then the reaction will have fast equilibrium.
What happen to reaction if one mole hydrogen ions and one mole of hydroxide ions?
They will form one mole of water.
What does NADPH provide in the Calvin benson cycle?
NADPH adds electrons and hydrogen ions to the Calvin-Benson cycle.
Describe why the indicator reaction is pH dependent?
An indicator reaction is always pH dependent because it involves hydrogen. During the reaction, hydrogen ions are either released or captured during the process.
Which reaction adds hydrogen ions to the blood?
nitrogen
Why do you think no reaction occurs between acidified hydrogen peroxide and halide ions other than iodide?
No reaction occurs between the acidified hydrogen peroxide and the other halide ions, because the hydrogen ions involved in both cases are in the same group. For a reaction to occur it needed to have an element that is more reactive than hydrogen.

Why are hydrogen ions and hydroxide ions omitted from the net reaction for the hydrolysis of water?
The two ions tend to recombine to form liquid water
What substance adds or removes Hydrogen ions from a solution?
metals and salts that precipitate it - e.g silver nitrate would remove OH ions from solution. Acids would also tend to remove OH ions from solution
What happen to reaction if one mole hydrogen ions and one mole of hydroxide ions?
They will form one mole of water.
What will be the product when reaction between water and carbon will occur?
Carbonic acid. The reaction is: H2O + CO2 -----> H2CO3 ----> H+ + HCO3- The reaction is catalysed by an enzyme called carbonic anhydrase. After it has formed it separates (dissociates) into hydrogen ions (H+) and hydrogen carbonate ions (HCO3-).
What is an example of a redox reaction?
One example of a redox reaction is the reaction between magnesium metal and hydrochloric acid to form magnesium chloride and hydrogen gas. In this reaction, magnesium is oxidized (loses electrons) to form Mg2+ ions, while hydrogen ions in the acid are reduced (gain electrons) to form hydrogen gas.
What does NADPH provide in the Calvin benson cycle?
NADPH adds electrons and hydrogen ions to the Calvin-Benson cycle.
Describe why the indicator reaction is pH dependent?
An indicator reaction is always pH dependent because it involves hydrogen. During the reaction, hydrogen ions are either released or captured during the process.
What is the difference between activation polarization and concentration polarization?
Activation polarization refers to a condition when the reaction rate (of oxidation or reduction) is controlled by the slowest "step" in a series of reaction steps. For example, in hydrogen reduction reaction, the first step (1) may be when hydrogen ions absorbed from solution onto the anode surface, (2) then electron transfer occurs from anode to the hydrogen ions to form hydrogen, (3) then the hydrogen elements form hydrogen gas molecules, (4) which then form hydrogen gas bubbles. The slowest of these 4 steps, dictates how fast the overall reduction reaction happens. Concentration polarization refers to a condition of the limits of diffusion. Basically, again referring to the hydrogen reduction reaction, the concentration of H+ ions around the cathode affects the reaction rate. It could be that the concentration is too high (there is plently of H+ ions around, or the concentration is too low (not enough H+ ions around or the reduction reaction is 'eating them up' too quickly).
